Stran 144 - The two groups are also referred to respectively as the "light" and "heavy" rare earths. The properties of the members of the two groups of rare earths are sufficiently distinct to cause one group to predominate over the other in most minerals, even though all or nearly all are ordinarily present (Olson and Adams, 1962) . The rare earths have many industrial applications such as in the steel industry, nonferrous alloys, glass manufacture and glass polishing, sparking alloys, and carbon electrodes...

Some helium occurrences in natural gas are given in table 14. In 1961, helium-bearing gas (sample No. 1, table 14) was discovered in the Paradox Member of the Hermosa Formation of Pennsylvanian age in the Table Mesa field. The field has an estimated recoverable helium reserve of 850,000 MCF (thousand-cubic feet), and...

Stran 366 - Significant quantities of the element were used in plastics, flameproofing chemicals and compounds, pigments, and in ceramics and glass (Spencer and den Hartog, 1963a, table 7). Although antimony possesses no indispensable properties, it is technologically superior to other elements in many of its uses. Furthermore, it is relatively inexpensive and can be substituted for more expensive metals.
